3. two mathematicians are neighbors. each owns a separate rectangular plot of land that shares a boundary and has the
same dimensions. they agree that each has an area of 2x2 + 3x + 1 square units. one mathematician sells his plot to
the other. the other wants to put a fence around the perimeter of his new combined plot of land. how many linear
units of fencing does he need? write your answer as an expression in x.

Step-by-step explanation:

The factors of the given polynomial are (2x+1) and (x+1). We presume these are the side lengths of each rectangular plot. If the short side (x+1) was common, then the perimeter of the combined lot is ...

  4(2x+1) +2(x +1) = 10x +6 . . . units of fence for short side common

If the long side (2x+1) was common, then the perimeter of the combined lot is ...

  4(x+1) +2(2x+1) = 8x +6 . . . units of fence for long side common

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
